UNITED STATES PATENT OFFICE.

BUISSON PIERRE, on NEW YORK, N. Y.

IMPROVED ARTIFICIAL FUEL.

Specification forming part of Letters Patent N0. 42,163, dated April 5,1864.

To all whom it may concern:

Be it known that I, BUIssON PIERRE, of the city, county, and State ofNew York, have invented a new and improved mode of making out ofanthracite dust good light-burning coal or an imitation of Liverpoolcoal; and I do hereby declare that the following is a full and exactdescription of the said invention.

The nature of my invention consists in mixing with anthracite-coal dustthe residuum of petroleum distillation in a pulverized state, and thensubmitting the same to a sufficient heat to melt such residuum and causethe particles of coal to adhere together. There remains in the stillafter the distillation of petroleum a thick residuum of a natureresembling coke and tar. This is the material I employ. The same is tobe ground and mixed with the coal-dust in the desired proportionfromfour to ten per cent. The mass is then placed in molds of any desiredshape or size,

| or in pans, and subjected to a sufficient heat to cause the petroleumresiduum to melt and unite the particles of coal. The mass may bepressed to produce greater consolidation. If

the proportion of petroleum residuum is large,

the coal will burn like Liverpool or cannel coal; if smaller, the firewill be'nearly like the ordinary anthracite.

I do not claim tar or asphaltum for uniting the anthracite-coal dustinto blocks or lumps; but

What I claim, and desire to secure by Letters Patent, is

Uniting anthracite-coal dust with petroleum J. BURNIER, F. F. BADOYE.
